There should be a file in the NoSpam! zip you got called troubleshooting.txt. This describes the template edits you need to make to make NoSpam! appear on each of the supported pages if it does not work immediately upon installation. Follow the instructions for those pages you have enabled where it is not working. The integration file is about integrating NoSpam! with other hacks and is not relevant to your case if you don't need it integrated with other hacks.

Those four options are the pages you can select for it to appear on, as they are the only places in the forum at which I could picture NoSpam! as being remotely useful. The change since version 2.0 is that now you can choose to disable it for one or more of those pages, while previously it would always appear on all of them. Make sure you at least have it set to be enabled at registration, and perhaps the others if you would like that; now follow the instructions for template edits in the troubleshooting.txt file you downloaded for each page you enabled where it is not appearing. For example, if you enabled it at registration but not at the Contact Us page, you should follow the instructions under REGISTRATION, but not those under CONTACT US.
